Hafnium(IV) Nitrate Hf(NO3)4

Product Information

Nano Hafnium Oxide Powder is an intermediate in some processes that give hafnium metal. Hafnia is used in optical coatings, and as a high-κ dielectric in DRAM capacitors and in advanced metal-oxide-semiconductor devices. Because of its very high melting point, hafnia is also used as a refractory material in the insulation of such devices as thermocouples, where it can operate at temperatures up to 2500℃. Multilayered films of hafnium dioxide, silica, and other materials have been developed for use in the passive cooling of buildings.

ATT specializes in producing spray dry and non-spray dry high purity Hafnium Oxide Powder with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD), Metallic-Organic and Chemical Vapor Deposition (MOCVD). Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. Our standard powder particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron) and our spray dried powder with binder provides an extremely narrow particle size distribution (PSD) for use in thermal and plasma spray guns and other coating applications. We can also provide many materials in the nanoscale range.

Hafnium Nitrate is a moderately water soluble crystalline Hafnium source that decomposes to Hafnium oxide on heating.   It is generally immediately available in most volumes.   Acetates are excellent precursors for production of ultra high purity compounds and certain catalyst and nanoscale (nanoparticles and nanopowders) materials.   All metallic acetates are inorganic salts of a metal cation and the acetate anion.   The acetate anion is a univalent (-1 charge) polyatomic ion composed of two carbon atoms ionically bound to three hydrogen and two oxygen atoms (Symbol: CH3COO) for a total formula weight of 59.05.   Ultra high purity, high purity, submicron and nanopowder forms may be considered.   Nitrate compounds are generally soluble in water.   Nitrate materials are also oxidizing agents.   When mixed with hydrocarbons, nitrate compounds can form a flammable mixture.   Nitrates are excellent precursors for production of ultra high purity compounds and certain catalyst and nanoscale (nanoparticles and nanopowders) materials.   All metallic nitrates are inorganic salts of a given metal cation and the nitrate anion.   The nitrate anion is a univalent (-1 charge) polyatomic ion composed of a single nitrogen atom ionically bound to three oxygen atoms (Symbol: NO3) for a total formula weight of 62.05.
